I need help programming USB FS on Nucleo-F303RE. using pins A11 and A12 and connecting via an exposed USB cable using wires for direct connection to the GPIO's

I believe the programming code might be missing something. I was missing external 1.5K pull up resistors, but I added them and the device is recognized over USB.

I would like code references, to implement mass storage mode, with SD card (via SPI).

I believe that programming code may be missing, as the external 1.5K pull up resistors I added. I tested to do HID, Virtual COMport and Mass Storage, none gave a signal.

I would like examples of Mass Storage and COMPort to check if I missed something, or if suddenly it's jumpers on this core board that are incorrect.

The DFU_Standalone example is available in STM32CubeF3, this example has been tested with STM32F303RE-Nucleo Rev C board. Please check the STM32F303RE-Nucleo Rev C Set-up in the readme file.

Also, MSC_Standalone and CDC_Standalone examples can help you, these examples has been tested with STMicroelectronics STM32373C-EVAL RevB evaluation boards and can be easily tailored to any other supported device and development board.
